CR10-S & Cura 4.1.0 problems

I have a CR10-S and have been running it using Cura 3.6.0 and then Cura 4.0.0 without any problems. However Cura then issued an update to Cura 4.1.0 and since then I have had a lot of problems. I can upload a file into the program and adjust the printing settings as required but as soon I try to print the program just shuts down. I have tried clearing all Cura files from my computer and doing a complete fresh install but the the problem occurs. Thought I would go back to using Cura 4.0.0 but the same problem is occurring on that version. I have resorted to reinstalling Cura 3.6.0 and I am using that.
Has any one got any suggestions on this as Ultimaker day they do not offer support on the Creality printers. What printing software do you use. Forgot to add the the computer is fairly new only being 1 year old and using Windows 10. Any suggestions would be appreciated.
